Located north of Leyburn QLD, you can find a monument at the site of the 1949 Australian Grand Prix Motor Racing Circuit. The monument sits directly on where the historical airfield runway from the RAAF Leyburn Airfield 
crosses the road. There is some irony in using the abandoned WWII airstrip, as the races were abandoned for seven years during the war, from 1940 to 1946.
The Leyburn Australian Grand Prix was the third race after reintroducing the annual race in Australia. The first was held at Mount Panorama in Bathurst NSW, the second was held at the RAAF airfield in Point Cook VIC.
The monument is on the side of the road that was part of the main straight of the circuit. We followed the brown signs, including the historic airfield, when we went to the Royal Hotel in Leyburn as part of a pub camp every month 
tour we were doing in 2025.
A plaque on the monument states the following:
Queenslands first Australian Grand Prix for motor cars was held on this site on 18th September 1949. This was the 14th Grand Prix in Australia and featured the first massed start in an Australian Grand Prix. More than 30,000 sepctators attended.
This memorial celebrates the event and 50 years of motor sport in Queensland.
Erected by the Historic Racing Car Club (Qld) Inc. and the Citizens of Leyburn and Clifton on 18-9-1999.
Under the plaque is another illustrating the map of the circuit, and where the monument is located on the circuit.
Leyburn hosts an annual Historic Leyburn Sprints , celebrating their 29th anniversary in 2025, 76 years after the 1949 Australian Grand Prix race. The original circuit no longer exists, now mostly on private properties. The sprints are run around the Leyburn township with registrants driving around the track individually in attempt to get the fasted lap time.
